Sharing Mac but making sure the data can only be read
I need to find a way to share my Mac with someone but to make sure he has no way of downloading anything or even copying anything - sort of making my entire Mac read only (not only preventing external insertions but also not allowing the downloading or even copy pasting of files or lines of code.) tried finding anything for that online unsuccessfully. Any suggestions?

How to fix "segmentation fault 11" when running code in terminal?
I am having issues running my code through terminal on macOS. The code takes 2 binary text files, and convolves the two signals. I first use
gcc program.c -o execute
to execute the code, and then I use./execute dataFile outputFile imuplseFile
to run the code. When I do this, I get the error code of segmentation fault: 11. I know that seg faults occur when memory that shouldn't be accessed is accessed with the code, but I can't find any place where this is occurring. When this occurs, my output file, y, has no data in it. If I run the code in Xcode instead of command line, I don't get any segmentation faults and the output file, y, is filled with the correct data. Is there any reason that running this program in the command line would change the behavior of the code?FILE *fx, *fy, *fh; fx=fopen(argv[1], "rb"); fy=fopen(argv[2], "wb"); fh=fopen(argv[3], "rb"); int Lx, Lh, Ly, Lz; dsp_file_header headx, headh, heady; fread(&headx, sizeof(dsp_file_header), 1, fx); fread(&headh, sizeof(dsp_file_header), 1, fh); Lh=headh.dim0; Lx=headx.dim0; Ly=Lx+Lh-1; Lz=Lx+2*(Lh-1); memcpy(&heady, &headx, sizeof(dsp_file_header)); heady.dim0=Ly; fwrite(&heady, sizeof(dsp_file_header),1,fy); float *x=(float*)calloc(Lz, sizeof(float)); float *h=(float*)calloc(Lh, sizeof(float)); float *y=(float*)calloc(Ly, sizeof(float)); fread(x+Lh-1, sizeof(float),Lx,fx); int n, k; float t; fread(h, sizeof(float), Lh, fh); for(n=0; n<Lh/2; n++) { t=h[n]; h[n]=h[Lh-1-n]; h[Lh-1-n]=t; } for(n=0; n<Ly; n++) { t=0.0; for(k=0; k<Lh; k++) { t += h[k]*x[k+n]; } y[n]=t; } fwrite(y, sizeof(float), Ly, fy); fclose(fx); fclose(fy); fclose(fh); free(x); free(y); free(h);
I expect the resulting y file to be the result of convolving x with h, but when running the code through command line the resulting y file has no data. When running with Xcode, the resulting y file is exactly as expected.

Angular 6- Do my validations pose a security risk?
I am building an application with Angular 6 and want to know if I should avoid certain front-end validations. The validations in question include receiving a list of users from our API/server, each with a key/value pair of "enabled": "true/false". If the value is true, we will display the user's information. If the value is false, we will raise an error saying the user is unauthorized.
Is this something I should code into my Angular component? Or should this happen in the server before it even gets to the application? I thought that a user would be able to edit the source code via the browser developer tools and easily edit this check, to view information they shouldn't see. Is that true?
Thank you! I can't seem to find direct information on this. Any information/resources would be much appreciated.

Which meta tags are necessary to change in the head html tag in order to share custom images on social media?
I got all these lines in th head tags of my HTML page. I want to change the image when sharing it on social media depending of the url.
I already created a function to change the meta tag when the url matches a certain string.
Now I am wondering if I have to change only one meta tags or all of them including twitter & facebook? This is the current meta tags on my code:
<meta property="og:image" content="http://carrieres.mywebsite.com/static/img/opengraph-fr.jpg"> <meta property="og:image:url" content="http://carrieres.mywebsite.com/static/img/opengraph-fr.jpg"> <meta property="og:image:secure_url" content="https://carrieres.mywebsite.com/static/img/opengraph-fr.jpg"> <meta name="twitter:image:src" content="https://carrieres.mywebsite.com/static/img/opengraph-fr.jpg">
Which ones I need to change? I want to make sure before pushing to staging cause on my local environment I cannot test if it work when sharing on social media

Why won't Android Studio recognize the setShareContent() method for my ShareButton when trying to use Facebook SDK?
I'm learning how to implement a button that I can use to have users share content from my Android app to their Facebook timeline. Using a mixture of tutorials and the Facebook Developer website. This is the class that I'm using but for some reason I'm getting an error of 'cannot resolve symbol setShareContent' even though this part is copied from the Facebook developer tutorial. What have I missed? I feel like there must be a missing import but I can't see what :/
package com.example.androidfacebooksharelinktutorial; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import com.facebook.share.model.ShareLinkContent; import com.facebook.share.widget.ShareButton; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } // Model the Facebook content to be shared ShareLinkContent content = new ShareLinkContent.Builder() .setContentUrl(Uri.parse("https://developers.facebook.com")) .setQuote("Connect on a global scale.") .build(); ShareButton shareButton = (ShareButton)findViewById(R.id.share_btn); shareButton.setShareContent(content); }

How to improve message security performance over the internet (WCF)
My goal is to run scripts on a remote machine (which has local DB). For that I got a client which sending scripts to the target machine by WCF service which runs on the target machine (over the internet). The service is 'netTcpBinding' service with message security with mode of 'UserName'.
The problem starts when there are many tasks running in parallel using the network. The latency gets bigger and bigger. I know that message security has performance issues because of encryption and signing of each message. It's got already to 1 hour of latency in sum (nothing being changed in the amount of scripts), and it's quite consistent in the latency.
What will be the best option to improve that?
- Should I zip encrypted scripts and send them in one WCF message?
- Should I send folder of encrypted scripts by some sort of copy ( should I concern about whether File.Copy() considered as secured if my scripts are secured?)? What would be the right secure copy to a UNC path?
- Another best-practice option?
Thanks

Choosing server architecture for home made file sharing and media streaming server
I'm thinking about converting my old desktop PC to a server for my home made file sharing and media streaming server. I'm just not sure as to which architecture I should use for the server. My thoughts are to make a RESTful server but the client will NOT be in the web-browser as I don't have too much experience with HTTP(S) coding (yet).
Which architecture would you recommend for a system like this? Please keep in mind that I've only worked with the theoretical parts of PRC and REST therefor if any other architecture should be a better/easier solution I'd really appreciate a reference to some liturature to get started.
Thanks in advance!
